My 5 year old son was diagnosed with exophoria, as of right now he can write, read numbers and letters from all distances. Will his exophoria get worse? What are some exercises we can do at home to help strengthen the eye? You said you have exophoria, do your eyes ever go outwards or cause you any problem? What age did you find out you had exophoria. Since we caught his so early is there a chance we can strengthen the muscle enough to where it won't cause any problems? Is a lazy eye worse then exophoria? I'm worried about my son I want him to grow up and be as smart as I know he is. Everyone I talk to has never heard of exophoria, is it as bad as I'm making it in my mind.
